kerasTUT 6-CNN tutorial needs update

[EmbraceLife]

I have tried to update this tutorial to the latest keras. However, it seems the problem to be keras source code, because I tried to use the latest api, but the error it reported is located in keras source.

However, I am a newbie, so I maybe totally wrong. Could you try to update this tutorial, thanks a lot!

I have managed to update part of the tutorial until I met the error:

# Another way to build your CNN
model = Sequential()

# here explain the meaning and effects of number of filters  https://youtu.be/zHop6Oq757Y?list=PLXO45tsB95cKhCSIgTgIfjtG5y0Bf_TIY&t=250
# Conv layer 1 output shape (32, 28, 28)
model.add(Conv2D(
    filters=32,
    data_format='channels_first',
    kernel_size=(5,5),
    padding='same',     # Padding method
    dim_ordering='th',      # if use tensorflow, to set the input dimension order to theano ("th") style, but you can change it.
    input_shape=(1,         # channels
                 28, 28,)    # height & width
))

model.add(Activation('relu'))

# Pooling layer 1 (max pooling) output shape (32, 14, 14)
model.add(MaxPooling2D(
    pool_size=(2, 2),
    strides=(2, 2),
    padding='same'   # Padding method
))

error message I got:
